Msika wapano wa epoxy resin ukupitiliza kukhala waulesi.Bisphenol A yaiwisi idatsika moyipa, epichlorohydrin idakhazikika mopingasa, ndipo utomoni udakwera pang'ono.Okhala nawo anali osamala komanso osamala, akumayang'ana kwambiri pazokambirana zenizeni.Komabe, kufunikira kwa katundu kunsi kwa mtsinje kumakhala kochepa, ndipo kuchuluka kwenikweni kwa katundu pamsika sikukwanira, zomwe zimapangitsa kuti pakhale mpweya wofooka.Pofika tsiku lotsekera, mtengo wokambirana wa East China liquid epoxy resin ndi 13500-13900 yuan/tani ya madzi oyeretsedwa kuchoka kufakitale;Mtengo wokambitsirana wa Mount Huangshan solid epoxy resin ndi 13400-13800 yuan/ton, woperekedwa ndi ndalama, ndipo cholinga chazokambirana ndi chokhazikika komanso chofooka.
Mkhalidwe wamalonda pamsika wa epoxy resin ku South China ndi wofooka, ndipo pakali pano pali nkhani zochepa za malonda amsika m'mawa.Mafakitole akupereka mwachangu maoda atsopano, ndipo malingaliro akunsi kwa mtsinje siwokwera.Kukambitsirana kwakukulu kumanena kwakanthawi ku migolo ikuluikulu ya 14300-14900 yuan/tani kuti ivomerezedwe ndi kutumiza, ndipo mitengo yotsika mtengo yotumizira siili yosalala.
Msika wamadzimadzi wa epoxy resin kudera la East China uli ndi njira yogulira pang'ono, ndikutsika kwakukulu kwazinthu ziwiri.Mafakitale ena a utomoni anena za mitundu yopapatiza ya madongosolo atsopano, zomwe zimapangitsa kuti zikhale zovuta kuti akambirane.Kugula kwapansi ndi kopepuka, ndipo zokambirana zazikuluzikulu zikungoyang'ana kwakanthawi kuvomereza ndi kutumiza migolo ikuluikulu ya 14100-14700 yuan/ton.
Msika wolimba wa epoxy resin ku East China ndi South China ndiwopepuka komanso wadongosolo, ndikuchita mofooka m'misika ya bisphenol A ndi epichlorohydrin.Ntchito yonse yothandizira ndalama ndi yofooka, ndipo kutumiza maoda atsopano a epoxy resin olimba sikosalala.Opanga ena amatha kukambirana kuti maoda atsopano atumizidwe pamtengo wotsika.M'mawa, zokambirana zazikuluzikulu pamsika waku East China zimatengera kwakanthawi kuvomereza ndi kutumiza 13300-13500 yuan/tani, pomwe zokambilana zazikuluzikulu pamsika waku South China zimangotanthauza kuvomereza ndi kutumiza 13500-13700 yuan/ton kwakanthawi. .
Supply and demand situation:
Mbali yamtengo:
Bisphenol A: Msika wapakhomo waposachedwa wa bisphenol A uli ndi mpweya wopepuka, womwe umakonda kutsika pang'onopang'ono.Kuonjezera apo, msika wofooka wazitsulo umapitirirabe, ndipo msika uli ndi mlengalenga wolimba wodikira ndikuwona, ndi mafunso ochepa omwe atsala.Msika waukulu ku East China unanena mtengo wa 9550-9600 yuan/tani mkati mwa tsiku, ndi zokambirana zapakati kufika kumapeto kwa 9550 yuan/ton.Zamvekanso kuti mitengo ndi yotsika pang'ono, kuchepa kwa 25 yuan / tani poyerekeza ndi dzulo.Opanga kumadera aku North China ndi Shandong akutsatira zomwe zikuchitika pamsika, ndipo chidwi cha malonda pamsika chatsika pang'ono.
Epichlorohydrin: Masiku ano, ECH yapakhomo ikupitirizabe kusintha kwake.Pakali pano, msika wadzaza ndi mpweya, ndi opanga makamaka kutumiza pamtengo wapamwamba.Komabe, mkhalidwe wa kufunikira kofooka sikunasinthe, zomwe zimapangitsa kuti opanga apitirizebe kukakamiza kuti atumize ndi kutsika kwa msika wamtsogolo.Malamulo atsopano nthawi zambiri amapitilira kugulitsa pamitengo yotsika, ndipo palinso mphekesera zamitengo yotsika pamsika, koma kuchuluka kwa dongosolo lenileni sikukwanira.Potseka, mtengo wokambirana m'misika ya Jiangsu ndi Mount Huangshan unali 8400-8500 yuan/ton kuti avomerezedwe ndi kutumizidwa, ndipo mtengo wokambirana m'misika ya Shandong unali 8100-8200 yuan/ton kuti avomerezedwe ndi kutumiza.
Mbali yofunikira:
Pakali pano, chipangizo chonse katundu wa madzi epoxy utomoni ndi pamwamba 50%, pamene lonse chipangizo katundu wa olimba epoxy utomoni ndi mozungulira 40%.Kufuna kutsika kwatsiku kotsatiridwa ndi kochepa, ndipo kuchuluka kwenikweni kwa kutumiza sikukwanira, zomwe zimapangitsa kuti msika ukhale wodekha.
